Just got my smog notice (not test-only) and I'm worried as hell! Car has long tubes with O2s, catted TSP Y-pipe, 224/224 cam with 114 LSA, 160* stat, and what smells to be a fairly rich tune! All smog equipment is functioning. My main concern are the long tubes and Y-pipe because there is no CARB# and the cats I know can't legally be changed from stock and have to be in the stock location. So I won't pass visual. My tuner says my setup will pass emissions testing physically, but it smells a little rich to me. The cam is small and has minimal overlap so I'm not too worried about that, but I wonder if the tech will hear the cam and know its not stock. I don't want to throw my stock exhaust back on, I want to try to pass as is but how can I get around the visual assuming I pass the actual test? If I have to change out the cam for stock I'm gonna cry.
